Does AWeber use SPF Authentication?

Sender Policy Framework (SPF) is a standard for authenticating email. It is used by ISPs to ensure that purported senders of email messages are actually the ones presenting the messages they review.

AWeber authenticates using SPF

In order to ensure optimal deliverability of messages, AWeber does authenticate using SPF. While this means that you will most likely not encounter any deliverability issues when using your website's domain in your from address with AWeber (i.e. you@yoursite.com), it is still a good idea to make sure that you've added 'include:send.aweber.com' to your domain's SPF record.
